PROBLEM TO BE SOLVED: To provide a non-contact data reception/transmission body that can make communication distance longer in the state of having the body get close to a metal body and can make it thinner without conducting complicated antenna design or the like.SOLUTION: A non-contact data reception/transmission body 10 comprises: an inlet 30 that is used by pasting it to a metal body 60 and includes an IC chip 32 and a first antenna 31 connected with the IC chip 32; a second antenna 40 that is arranged along the first antenna 31 in the state of non-adhesion with the first antenna 31, and is for a booster; and a support member 50 that supports the inlet 30 and the second antenna 40 and is composed of dielectric. The shape of a cross-section along the thickness direction and longitudinal direction of the support member 50 forms an arc such that the support member gradually distances itself from the metal body 60 from its both ends 50c, 50c toward its central part 50d. The IC chip 32 is placed at the top of the support member 50.SELECTED DRAWING: Figure 1 |
